The same phenomenon can be found in raster datasets, where the advances in hardware are responsible for an important increment of the size and the amount of available data. The advance of the digital society is providing a continuous growth of the amount of available vector data, but the appearance of cheap devices equipped with GPS, like smartphones, is responsible for a big data explosion, mainly of trajectories of moving objects. When dealing with spatial data, depending on the particular characteristics of the type of information, it may be more appropriate to represent that information (at the logical level) using either a raster or a vector data model.
